China Friday quotes: Force India

Tonio Liuzzi - 16th: It was difficult out there today. The prime tyre, which was my first run of the day, was good. The car was behaving well but then after we changed to the soft tyre we were sliding all over the place and struggling to get the temperatures in the tyres. It was a big frustration as the car was not there any more. It was strange as it was such a clear change from hard to soft. We need to look into this problem but I think we can be positive about the rest of the day as on the hard tyres we seem to be quite strong.

Paul di Resta: It was a very difficult session as the conditions were quite tough out there. The track was green with little rubber to start with and the low temperatures and the hard tyre compound made grip levels very, very low. I still managed to learn a few things about the car and of course the circuit. It's a tricky track with some blind corners and variety of speeds and it's hard to get into an easy rhythm straight away. Unfortunately I flat-spotted one of the front tyres, which compromised how much I could get out of the last two runs but we still got what we wanted out of the session and I have learnt another track so, all in all, it was productive day.

Dominic Harlow, chief race engineer: Sunny but still quite cold today. The early track grip has been low, and the tyres a little difficult to warm-up, that's all as expected really. We have a reasonable balance, but need to work hard to get the grip. With Paul driving Tonio's car in FP1, we ran our usual combination of tyre evaluation and set-up programmes between the three drivers, and apart from a couple of small issues in FP2 and the bigger bumps this year, it was a reasonably smooth day.
